Lesson 2: Understanding the meaning of the Declaration of Faith: "Ashhadu An La Ilaha Illa Allah, Wa Ashhadu Anna Muhammadan Rasul Allah" and to know the conditions of the statement: "La Ilaha Illa Allah." The meaning of the Declaration of Faith is: I bear witness that there is no god worthy of worship except Allah, and I bear witness that Muhammad is His Messenger. The phrase "La Ilaha" negates the existence of all deities, while the phrase "Illa Allah" confirms Allah's right of Lordship and Godship, Who Alone deserves to be worshipped.
The conditions of "La Ilaha Illah Allah" are as follows: knowledge that negates ignorance, certainty that negates doubt, sincerity of worship that negates polytheism, truthfulness that negates lying, love that negates hate, complete submission that negates rebellion, acceptance that negates rejection, and the rejection of all those that are unjustly worshiped besides Allah (Glorified and Exalted be He).
